The data was not digital, selleck compound but was produced as hard copies. However, the spin-off of the remote sensing developed for military purposes during the above 3 eras spilled over to mapping and slowly into environmental and natural resources applications.Meteorological satellite sensor remote sensing era: The early meteorological satellite sensors selleckchem consisted of geo-synchronous Geostationary Operational Environmental Satellite (GOES) and polar-orbiting National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) (Kramer, 2002). This was an era when data started being available in digital format and were analyzed using exclusive computer hardware and software. This was also an era when global coverage became realistic and environmental applications practical.
Landsat Inhibitors,Modulators,Libraries Inhibitors,Modulators,Libraries era: The Landsat era begins with Inhibitors,Modulators,Libraries the launch of Landsat-1 (then called Earth Resources Technology Satellite) in 1972 carrying multi spectral scanner (MSS) sensor. This was followed by other path-finding Landsat satellites 2 through 3 which carried MSS and 4 and 5 which carried Thematic Mapper (TM). The Landsat 7 carries Enhanced Thematic mapper (ETM+) sensor. The Landsat-6 failed during launch. The Landsat-8 carrying Operational Land Imager (OLI) is planned for launch in 2011. The Landsat era also has equally good sun-synchronous Land satellites such as Systeme Pour l’Observation de Ia Terre (SPOT) of France and, Indian Remote Sensing Satellite (IRS) of India (Jensen, 2000).
These satellites have high resolution (nominal 2.5-80 meter) and have global coverage potential.
At this resolution, only Landsat Inhibitors,Modulators,Libraries is currently gathering data with global wall Inhibitors,Modulators,Libraries to wall coverage. This is, by far, the most significant Inhibitors,Modulators,Libraries era that kick started truly wide environmental application of remote sensing data locally and globally.Earth Observing System era: The Earth Observing System (EOS) era (Stoney, 2005, Inhibitors,Modulators,Libraries Bailey et al., 2001, Jensen, 2000, Colwell, 1983) began with launch of Terra satellite in 1999 Anacetrapib and has brought in the global coverage, frequent repeat coverage, high level of processing (e.g., georectified, at-satellite reflectance), easy and Inhibitors,Modulators,Libraries mostly Cilengitide free access to data.
KRX-0401 The Terra\Aqua satellites carrying sensors such as Moderate Resolution Imaging Spectroradiometer (MODIS) and Measurements of Pollution in the Troposphere (MOPITT) have daily re-visit and various processed data. Applications of sensor data have become wide spread and applications have multiplied. Institutions and individuals http://www.selleckchem.com/products/tofacitinib-cp-690550.html who never used remote sensing have begun to take an interest in remote sensing. Also, the availability of the processed data in terms of products such as leaf area index (LAI) and land use\land cover (LULC) have become routine. Currently, MODIS itself has 40+ products.
